The ylabel position is layed out to not overlay the y tick labels --
if these are in different positions on each axes you will get the
ylabel in different positions.  Two solutions:

 1) insure all the yticklabels have the same width by using a custom
formatter that fixes the tick widths.

  from matplotlib.ticker import FormatStrFormatter
  ax.yaxis.set_major_formatter(FormatStrFormatter('%1.3f'))


  2) do not use ylabels, but create your own using custom text
instances for labels

  ax.text(-0.1, 0.5, 'my label', transform=ax.transAxes, rotation=90,
ha='right', va='center')

The 2nd one is probably what you want.
